The check engine light on a Dodge Avenger can stay on for various reasons, including a malfunctioning sensor, such as the oxygen or mass airflow sensor, issues with the engine's emissions system, or a loose or damaged gas cap. It may also indicate problems with the ignition system, fuel system, or other engine components. To diagnose the exact cause, it's essential to use an OBD-II scanner to read the trouble codes stored in the vehicle's computer. Addressing the issue promptly can help prevent further engine damage and improve vehicle performance.
